Also secured on the shafts 7 and 8, for movement therewith are thesecondary operating levers 13 and 14 respectively, two pairs of suchsecondary operating levers being provided as clearly indicated in thedrawings, and each pair is arranged inwardly of the respective ends ofthe frame 1. The secondary operating levers are slightly inclinedupwardly and a roller 15 is carried by the outer end of'each of thesesecondaryoperat.

ing levers for a purpose to be presently described.

Crossbars 16 extend transversely across the top of the frame 1,inwardlyof the re spective ends thereof to provide a support upon which the corepan 17 andthe core box.

18 are adapted to rest when in a normally open horizontal position, assuggested in Figure 1. Lugs 19 extend outwardly from the respective endsof the core pan 17 and similar lugs 20 extend from the outer ends of thecore box 18. The core pan and core box are constructed principallyforuse in the formation of a heat radiator core. The core pan is notconnected to the core box, but the manner in which these elementscooperate with each other will be presently described in detail.

Adj ustably connected hook shaped brackets 21 and 22 are arranged at therespective end portions of the frame and the outer ends of thesebrackets are formed with the lug receiving notches 23 and 24respectively. The laterally projecting lugs 19 associated with the corepan 17 normally rests within the notches 23 of the respective brackets21,

while the lugs 20 thatextend laterally from the core box 18 are adaptedfor disposition within the notches 24 of the complementary brackets 22,and this is clearly indicated in Figures 1 and 5 of the drawings. Thesecuring means for the overlapping inner ends of the complementarybracket shown is at 25, while in Figures 7 and 8 there is disclosed indetail the specific construction of each of these brackets.

.A rod '26 extends longitudinally of the frame 1 and is secured at itsends to the intermediate portions of the forward and rear ends of theframes 1. A pair of stationary brackets 27 have their intermediateportions secured on the rod 26, and these brackets are disposed in asubstantially horizontal plane as clearly indicated in Figures 3 and 4of the drawings.

Cam arms 28 and 29 are pivotallyconnected attheir inner opposed ends tothe respective ends of each stationary bracket 27.

Each of thesecam arms is in the form of a relatively thin bar or strip,the lower end of which constitutes a cam face for cooperation with theroller 15 of the respective secondary operating lever as clearlysuggested in Figures 3 and 4 of the drawings. The outer free ends ofthese cam arms are adapted to rest within suitable cut-out portions 30provided therefor in the respective sides of the recs tangular frame 1,as clearly shown in Figure 3. Furthermore, each cam arm is formed with alongitudinally extending slot 31, in which is operable a pin 32, thatextends laterallyfrom the lower end of a leg 33, that is'secured at itsupper end to a horizontally disposed shoe 34. A roller is carried byeach vertical leg member for engagement with the upper edge oftherespective cam arms and there are as many leg members and shoes asthere are cam arms.

The shoes 34 are furthermore adapted to engage with the bottomsof thecore pan and core boxes 17 and 18 respectively, when the latter aredisposed in their normal horizon tal open positions, and this is alsoshown very clearly in Figures 3 and 4 of the draw-.

ings. Theshoes-34 will furthermore engage with the core pan and core boxwhen the latter are disposed in a vertical position as shown by thedotted lines in Figure 3. 7

Associated with each bracket'27 are. the upwardlydisposed adjustablyconnected trip dogs 36, and 37 respectively. The upper ends of the dogsare disposed adjacent the inner opposed edges or ends of the respectivepair of shoes.

The trip dogs 36 and 37 keep the core pan and core box a correctdistance apart, as they 35 rise to the vertical position until the edgesof the pan and box meet and assume a vertical position. The dog 36furthertends'to stabilize the box and pan when they are lowered to ahorizontal position.

A pair of coil springs 38 are connected at their outer ends to theadjacent side of the frame 1, the inner ends of these springs beingconnected to pins 39 that extend from the inner side edge of the corebox 18. Additional coil springs 40 are connected, at their outer ends tosuitable brace bars 41 that extend across the frame, adjacent theforward and rear ends thereof. The inner ends of the springs 40 areconnected to a finger 42 7.3.:

that extends from each end of the core box 18 and is disposed through aslotted member 43 that is pivoted at its lower end on an up- INormally-the parts are arranged as shown i in Figures 1 and 5, whereinthe pan and box are disposed horizontally in an open position for restupon the cross bar 16. By operating the power operating rod 12, and topull the same to the right, the primary oper- An exten- 1::

ating lever 11 will actuate the shaft 8 and as the shaft 8 is geared tothe shaft 7 through the segmental gears 9 and 10, said shafts 7 and 8will rotate in unison towgard each other. This action results in thesecondary operating levers l3 and 14- being raised, and as the rollers15 engage with the cam faces of the respective cam arms 28 and 29, thelatter will swing upwardly by reason of their pivotal connection withthe stationary brackets 27. v 1

This upward movement of the cam arms results in the tilting of the shoes34 so that the core pan and core box will be swung upwardly toward eachother and the same will come in contact when in a vertical position andform the core from the sand that has, before the movement just begun.and by another mechanical arrangement (not shown) placed in the pan andbox.

The position of the parts when the core pan and core box are in avertical position is clearly shown in the dotted lines in Figure 3.After the core has been formed, the core box and pan are still incontact with each other and through the medium of the trip dogs 36 and37, the core box and pan will be caused to swing downwardly aleft handdirection to the position shown in Figure 6, whereupon the pan 17 will,again rest on the cross bars 16, while the box 1.8 will be disposed ontop of the pan. This movement of the pan and box from a vertical to ahorizontal position is further sisted through the medium of the springs40. The tension of the springs are released after the power on thetransmission rod 12 is released, but during the actuation of themechanism to dispose the core pan and core box in a vertical position,the springs 40 are placed under tension.

Subsequently the core box 1.8 is lifted off of the core pan,sufficiently to permit the pan and the core in the same to be removedand to permit the insertion of another pan. As soon as the core pancontaining the core ready for the oven is removed, and a new core pansub-- stituted in lieu thereof, the parts of the booking mechanism arereturned to their normal positions as shown in Figures 1 and 5.

The core can be backed in the exact condition and position it was inwhen booked.

The provision of a booking mechanism for a heat radiator core makingmachine will enable a perfect core to be formed. Furthermore, theimproved booking mechanism as described above will at all times bepositive and eflicient in its operation, and due to its simplicity,access to the several parts can be readily and easily had.

A booking mechanism of the above mentioned character can be constructedat a very low cost, and will furthermore be strong and durable.

While I have shown the preferred embodiment of my invention, it is to beunderstood that various changes in the size, shape and arrangement ofparts may be resorted to, without departing from the spirit of theinvention or the scope of the appended claims.
